I would suggest going down to a store that carries these and ask to have them turn it on. If it doesn't make a buzz, I would be surprised. Both the ones I have gotten from someone make a little noise. Not alot, but its just this little annoying hum.

I would suggest waiting until someone has a retro for sale in the forum that has both halides and vhos or just spring for a retro of either and add on later.
